Treasury of Architectural Structures of the Cultural Institute of Museums at the Foundation consists of three collections: 1) wooden structures (wooden doors, windows and ceilings), 2) ceramic works such as seven-colored tiles and mosaics, and 3) stone objects such as the base of stone columns. Wooden structures are dedicated to the maintenance of decorative wooden doors and windows, painted wooden ceilings, exquisite sash windows and mirror frames. This treasury holds various wooden works such as lattice work, inlay work and mosaic work, as well as different types of mirror works and paintings on the wooden works and wooden extensions in historical buildings from different eras (mostly Qajar and Pahlavi periods). For instance, there is a 900-year-old wooden door and doors with paintings on them from the Safavid period. Ceramic works include Zarrinfam (golden shade) ceramics, seven-colored tiles and mosaic tiles from different historical periods. The outstanding works of this collection are rare examples of tiles from the Seljuk and Ilkhanate eras. The stone works of this collection are mainly from the Qajar and Pahlavi eras, examples of which include stone lion sculptures (belonging to the tombs of Bakhtiari tribes).
